(a) At any time after the passage of the bond order, the governing body of a unit shall have full authority by resolution to provide for the issuance of the bonds authorized by such bond order. Such resolution providing for the issuance of the bonds may be introduced and finally passed at any regular or duly called special meeting of the governing body and shall be in force and effect from and after its passage.

(b) The governing body shall by resolution determine the rate or rates of interest to be paid on the bonds, and the time or times of payment of such interest, and the maturity or maturities of the bonds, which shall be at a time or times not exceeding twenty (20) years from the date of the bonds in the case of funding bonds, and not exceeding thirty (30) years from the date of bonds in the case of refunding bonds; provided, that with the approval of the comptroller of the treasury or the comptroller's designee, funding bonds may be made to mature at any time or times not exceeding thirty (30) years from the date of the bonds and refunding bonds may be made to mature at any time or times not exceeding forty (40) years from the date of the bonds.

(c) The governing body shall also by resolution determine the form of the bonds, the officers by whom they shall be executed and the place or places in Tennessee or in any other state at which the principal and interest shall be payable.

(d) In case any of the officers whose signatures appear on the bonds or coupons shall cease to be such officers before the delivery of such bonds, such signatures shall nevertheless be valid and sufficient for all purposes, the same as if they had remained in office until such delivery.

(e) The bonds may be made registrable as to principal alone and as to both principal and interest, under such terms and conditions as may be determined by the governing body, and provisions may be made for the exchange of fully registered bonds for coupon bonds and of coupon bonds for fully registered bonds.
